Bike— Part 1 채점 보고서

제안: 答题不够自然且时态错误。应该直接用过去时并扩展回答，给出一到两句具体细节（例如什么时候得到的、谁送的或经常骑去哪儿），并用连接词衔接句子以增加连贯性。注意最多不超过5句。

예시: Yes, I did. I got a red bicycle when I was seven, and my parents bought it for me as a birthday present. I rode it every day to visit my friends and explore the neighborhood, which helped me become more independent.

제안: 回答重复且有语法/拼写错误（countries应为country）。应给出一到两句具体原因或例子，使用连接词（like, because, for example）使回答更有说服力和细节。保持句子简洁，不超过5句。

예시: Yes, they are very popular. For example, many people use bicycles to commute to work and school because they are cheap and convenient, and cities often have bike lanes that make cycling safer.

× Yes, I have.

✓ Yes, I did.

该回答在问句使用过去时（Did you have...）的情况下，学生却使用现在时态的助动词 have（相当于"我有"或完成时），时态不一致。正确应该用过去式回答过去是否拥有某物，使用 did 或者直接过去式动词（例如："Yes, I did" 或 "Yes, I had"）。建议：注意根据提问时态选择相应的时态来回答。

× Yes, bikes are very popular in my countries.

✓ Yes, bikes are very popular in my country.

原句使用复数名词 countries 与语境不符（通常说某人的国家应为单数 country），且表述中应使用单数形式。建议：当指代自己所属的一个国家时使用单数 country；如果确实指多个国家，应明确说明并使用复数且改写句子。
